Japanese Patent JPH0142904
Kind Code:
B2
Abstract:
Raw material is fed to a preheater (1) and subsequently to a precalciner (3). The precalcined material, suspended in hot smoke gases, is fed to a separator (4). The separated material is divided into two subsidiary flows by a splitting gate (12), one subsidiary flow being fed via a pipe (13) to a pipe (18) where it is suspended in spent cooling air from a cooler (8). The suspended material is then fed to a reaction chamber (6) in which it is burnt and at least partially melted, the material subsequently being fed via a cyclone (5) to a rotating nodulisation drum (7). The other subsidiary flow is fed directly to the nodulisation drum (7) via a pipe (14).
